The summer Milky Way towering over the sandstone concretions and badlands at Red Rock Coulee Natural Area, in southeast Alberta. Taken July 26, 2017. Saturn is the bright object amid the Dark Horse dark lanes in the Milky Way at right. Sagittarius is just above the horizon amid some cloud. The bright star at top left is Altair in Aquila. This is a composite of 10 tracked exposures for the sky (mean combined to smooth noise) taken immediately after 4 untracked exposures for the ground (again, mean combined to smooth noise). Each exposure was 1 minute at f/2.2 with the Sigma 20mm Art lens and ISO 3200 with the Nikon D750. The tracker was the Star Adventurer Mini.
